ABSTRACT:
An apparatus for sealing and maintaining a desired temperature of a sample holder includes a non-deformable support, a deformable diaphragm secured to the lower surface of the support and a thermal regulable heater in thermal connection with the diaphragm. The apparatus can be positioned above the upper surface of a sample holder and, upon inflation of the diaphragm, a seal is formed between the diaphragm and the sample holder. When the thermoregulable heating element is activated, the sample holder is maintained at the desired temperature. The temperature can be coordinately regulated with a block heater that heats the underside of the sample holder.
